The Dreadbox White Line Modulator Eurorack Module is a pingable modulation source, which can operate as either an envelope or an LFO, it's taken directly from the modulation circuitry found in the NYX synthesizer.

Dreadbox Modulator is a unique modulation source, it features options to run as either an LFO or an envelope, with two variable speeds with attack and decay controls called rise and fall. It includes both gate and trigger inputs, so with a high value gate signal, the module is placed into a sustained state making it more like a static A/D envelope, or it can be pinged at the trigger input for shorter burst of modulation or even "in time" modulation if desired.

The White Line Modulator also includes CV control over the fall time of the module, making it particularly useful for dialing in longer, more drawn out humanised decay passages that can vary with the connect CV.
